Description

Invoking :PostToConnection works fine for the first few invocations

(-> (aws/client {:api               :apigatewaymanagementapi
                 :endpoint-override {:hostname "xxxxxxx.execute-api.eu-central-1.amazonaws.com"
                                     :path     "/xxxx/@connections/"}})

    (aws/invoke  {:op      :PostToConnection
                  :request {:ConnectionId "xxxxxxx"
                            :Data         "some data"}}))

but, after leaving it idle for about 5-10 mins then invoking it again, hangs on aws/invoke for about 5 minutes after which the following is returned as the result:

{:message "Signature expired: 20240425T100521Z is now earlier than 20240425T101638Z (20240425T102138Z - 5 min.)",
